More powerfull repeater?

Wow- got a quote back from this company and this is what they wrote-

Our price quote for 2.4GHz LHCP helical antenna is US$450 each.
Minimum order quantity is 2 units.
Estimated FedEx shipping cost for 2 units is US$150


that's ridiculous- a 'no go' for me

the other 'horizonfpvantennas.com ones look much more promising and affordable

Blackhawk 2.4 GHz Helical (LHCP) Heavy duty version
http://horizonfpvantennas.mybigcommerce ... y-version/

and

2.4 GHz Helical (LHCP) short lightweight version
http://horizonfpvantennas.mybigcommerce ... t-version/


though shipping to the US is fairly pricey

here's the email response on the antenna specs from horizonfpvantennas-

here are some dimension details

The BH+ Long heavy duty sizes


Width of reflector 9cm
Length of antenna 27cm
width of boom 4.5 cm
weight with pole clamp 280 grams or 9.7 oz


The BH+ Short heavy duty sizes

Width of reflector 9cm
Length of antenna 14cm
width of boom 4.5 cm
weight with pole clamp 230 grams or 7.7 oz



Nimrod 2.4 GHz sizes
width at base 8cm
width at top 4.5 cm
height 4 cm
weight 34 grams OR 1.2 oz


With you application, if the quad is using LHCP the BH+ H/duty long or short would work fine but a doubt if the antenna built into the camera transmitter is up to the mark.
A proper LHCP CP antenna would be better to give better results.


Ranges , well we have tests our set at over 11 km for RC control, It all depends on the power from the VTX as you know.


obviously adding an antenna to the p2v would help but I'm trying to avoid that and this seems to be best long range option without having to add anything to the p2v..

I want to Thank everyone who has posted to this forum!! I have learned more then I could by reading any book. I just finished my second complete reading of every post and have printed many posts and recommendations for future reference. I have purchased several antennas that I plan on installing as soon as the weather here in Ohio becomes suitable for flying.

But I still have a question that I can't understand. For those of you who fly out over 1,000 feet - how are you able to still see the P2V? On your return flight are you using Failsafe or Homelock or FPV? It appears that everyone is going up several hundred feet and then going forward until you loose video but how are you getting your P2V back home?

Thanks Again everyone. I've never been on a forum with such a diverse group of people from every part of this earth. Someday I'll probably look up and see one of you fly by on one of your long range tests.

If I still have FPV and know my orrientation, I use that to head home.
If I'm disorientated or don't have FPV, I use Radar.
If Wifi is lost, I switch to home lock and pull back on the stick.
If after a minute or so of home lock / pull back I still have no wifi, I engage RTH.

Thanks - when you switch to home lock and pull back on the stick do you need to worry about your altitude? Does home lock maintain your altitude like fail safe does when you are above 20 meters?

Home lock is just a way to control the phantom so it maintain the altitude in which it has.

When flying in GPS or ATTI mode, the P2V will (for the most part) try to maintain altitude in all conditions except when you specifically request a change in altitude. This is the same for Home lock, course lock, ...

Based on my experience, especially when flying beyond VLOS, I always maintain an altitude higher than the highest object between home and the P2V. Aside from losing FPV, the controller signal is easily obstructed and when lost will trigger RTH within about five seconds. RTH will take a direct path home (yes if you are below 20m it will climb to that altitude, but for any building, tree, water tower in it's way that is taller than that, it will fly right into it.) viewtopic.php?f=7&t=6616&p=50820&hilit=water+tower#p50820

you are right amigo, i will search and search and i found this, and looks good quality, so i let you know,

http://horizonfpvantennas.mybigcommerce.com/blackhawk-2-4-ghz-helical-lhcp-heavy-duty-version/

which one did you purchase- the big or smaller LHCP helical? look forward to hearing your results!

 

[gfredrone]

Helical Antenna

11dBi, 2370-2510MHz
RTight hand circular polarization
SMA female connector straight.
Includes a SMA male-male angled adapter

http://www.readymaderc.com/store/index. ... ts_id=1538

Would this work attached to the range extender to increase wifi distance?

Or how about this beast!

Sorry man, it wont work properly. If you read few pages back you would know that RHCP speaking to LHCP is even worse than linear to both of them. For FC200 camera you definetely need LHCP for best matching.

I emailed guys fromhttps://www.circular-wireless.com unfortunately they dont plan to release 2.4ghz LHCP one.

Hi,
I am afraid we only produce RHCP antennas, and we have no plans to produce LHCP versions in the short future. The only exception are the redundant antenna sets, but they are for 5.8GHz, not 2.4GHz.
Many thanks for your interest and you nice comments.
Kindest regards,
Juan Simo

see my posts ust above yours- links to 2 great helical lhcp antennas!

horizonfpvantennas.com in the UK

 

[BenDronePilot]

Found these LHCP helical antennas- http://www.antennaexperts.in/model-detail.asp?RecID=60

http://www.antennaexperts.in/product-de ... enna&id=17

don't know how reliable this company is - but if we could get a LHCP helical like this on the repeater only, will save having to add an antenna to the p2v camera/vtx, for optimal range..(since of course the stock p2v camera/vtx antennas are LHCP and because of the lack of LHCP antennas out there and an abundance of RHCP, to keep the match in direction of polarization when getting a helical antenna and only coming normally in RHCP, p2v camera/vtx antennas have needed to be changed to RHCP, but this may help avoid having to do that- I'd prefer not to have to add an antenna to the p2v as well because of added weight, drag, time to install and cost)

anyone think this LHCP helical could well well?

You can get better prices with Hobbyking. Link below.. Keep in mind from what I've seen thus far 2.4ghz Helical and skew planar style antennas all seem to be around the 2dbi range. So I don't really know what kind of boost you will see over stock in terms of flat out range, though You may get better signal at closer distances doing full rotation. I would like to know if anyone has found a higher gain antenna of that style. Also I was considering trying a 1.2ghz clover leaf antenna as it's larger than the 2.4ghz version in theory it should work too.

Will these work to increase my FPV wifi range?

or

My goal is to keep everything simple and as compact as possible. Also I'm not trying to set distance records I would just like some more FPV range. Thanks for any advice from the pros.

 

[BAKER_1111]

here is my set up i have 2 14 dbi directional antennas in the one case with 2 2w boosters and 2 omni antennas on each to i conected all of this with a 12v battery and the wifi extender also gets charged from this i put a swith to turn the hole system on or off it just hangs from the remote so you can put it anywhere i put a directional antenna on the 5.8 ghz remot and i put 4 clovers on the phantom itself the pics speak for themselvs i have not got a chance to fly it yet but flu it in the house lol

Yeah, wifi is very Convenient.

sorry Ben but as mentioned already those are all (as usual) only RHCP antennas and no good unless you're willing to add another RHCP antenna to the p2v camera/vtx as well to match..and the horizonfpvhobby LHCP helical antenna (larger one) is 12Dbi not 2dbi! If you go for an unmatched polarization you'll get a greater loss in range than matching RHCP to RHCP or LHCP to LHCP or linear to linear- anything else (eg. RHCP to LHCP or linear to LHCP etc) ..and the range will be less than optimal (same with trying to use a 1.2Ghz antenna with a 2.4GHz receiver/transmitter- they are mismatched and though may work somewhat , they won't be efficient to maximize their full potential for optimum range..

obviously the long heavy duty version will produce the greater range at 12dbi- I put the specs/dimensions etc for each antenna above- depends what works the best for your needs- greater range but carrying a bigger antenna or choose one of the smaller compromise antennas which will still provide great range with a smaller more convenient antenna but just not as much range as the larger/higher gain ones..again, looking at the specs the 2.4 GHz Helical (LHCP) short heavy duty version is 9dbi (1dbi more than the 8dbi panel antenna you linked)- so that would be the 'middle ground' but for max range obviously the long heavy duty one has the greater range..you choose what suits your needs best- I think even the 9dbi LHCP short heavy duty version will theoretically produce more range than the linearly polarized TP link 14 dbi panel/patch antennas seen a lot on these forums than are producing 3300 feet range because the LHCP helical is matched in polarization correctly with no loss in gain, plus because of the CP less likely to have to fly sideways at a distance that some people are reporting with linear antennas..
